As much as I wanted to go through with this, I knew that I couldn't handle it. The once-small preteen now looked like a professional weightlifter, and his cock looked big enough to snap me in half like uncooked spaghetti. I grabbed the flashlight, and immediately moved to shine it back on his Facebook image, when...
"Huh...?"
I stared at the screen, finding that was no longer idling on my brother's social media page, but instead displaying a black screen with the words "Windows is updating. 4%"
Fuck! A Windows Update?! NOW?!?!
"Hurry up, bro! Big Davey is really eager for his favorite cocksleeve! Heh..."
"Y-Yeah... Just gotta find where I left the lube..." I responded to my brother's growing impatience, while internally, I was panicking. I didn't have the option of using the flashlight on a picture anymore, and if I turned to try and use it on him directly, he was likely to just grab me, and fuck me into a catatonic state.
I could only come with one possible solution.
"I gotta break this thing..."
Breaking the flashlight would erase any changes that I made... or at least I hoped so, since it was my only play...
With the flashlight in hand, I raised it high up into the air, and slammed it down on the hardwood desk, as hard as I could
*SLAM*
It felt like the device had broken into at least 3 or 4 pieces, and thus I moved my hand to to see it, a small crack appeared on the light, and before I knew it both blue and pink light started to spill out of the damage device, until, a bright flash washed over me, forcing me to block my eyes from the brightness.
"Hm? You okay...?" My little brother asked, apparently noticing my odd movements.
"Oh, uhh... yeah. There was just a fly... it flew right into my eye... ha ha... ha..." I laughed awkwardly, trying to play it off.
As subtly as I could, I took a glance back to see my brother still sitting on the bed, and still looking like a 12-year-old God with a cock that would make a horse envious.
"Fuck... breaking it didn't do anything...?" I grumbled to myself.
I looked back down at the flashlight, to confirm that I had damaged the thing as much as I expected, but much to my surprise, it was completely intact, without even a scratch on it.
"Wait, what...?" I stared at the flashlight in confusion, "So, I can't break it...? What was that flash of light then? Did it do anything...?"
I stood there, completely lost, really unsure of how to even proceed, not that I had time to try anything else anyway... Within that next few moments, I felt a muscular hand slide up my sides, and rest on my hip. It appeared that Dave was done waiting.
"I'm thinking you probably got me slick enough with your tongue, bro. Forget the lube, My pre-cum is gonna make that tight femboy ass of yours more that slick enough, heh..."
"Wait... 'tight, femboy ass...'" I was six-foot-three, in decent shape, and had an eight-inch cock... I may not have been anywhere near as strong as Dave was now, but, I definitely was no femboy... I could tell something was different... and that's when I felt Dave's body against my back...
"I'm shorter than you?!?"
I looked at the glossy, still-mostly black computer screen and could clearly see my reflection. Gone was my fit, toned, tall form... replaced with the body of a short, slim, wide-hipped femboy. I was 19 years old, and not even as tall as my preteen brother! I had to be under five feet tall!
"Haha, don't act so surprised bro, I passed you in height a couple years back. It's cool though, I still love your little, girly body..." He slid his hands down to grip the sides of my shorts, and tugged them down, letting them slide down my legs, "Especially this part here..."
Before another moment passed, I felt him spread my ass, and his throbbing, warm tip begin to prod against my hole.
"Oh yeah... been waiting to do this all day..."
I felt him start to move, and I braced myself as best I could.
"MMMPPPH! Fuck, yeaaaah..." He let out a moan and the plum-sized head of his massive cock plunged into me.
"Ahh!" I instinctively let out a yelp before noticing that it... felt good...?
Dave pulled back just a little and pushed in again, stabbing about 6 inches, not even half... of his dick into me, and that confirmed for me. "Big Davey" plowing into me felt FUCKING AMAZING. In this universe I guess, I was so used to his giant dick, that I felt nothing but pleasure from his massive tool rearranging my insides.
"Ah! Fuck! M-More!" I moaned out as Dave started to move, I wanted... no, needed more of his cock... "Please! Fuck me deeper!"
"Hehehe..." He let out a low, evil laugh, "Well, since you asked nicely... let's bulge that belly out!"
